For the most part the composition looks good. The only weakness I see in the composition is the pattern created by the clouds repeating next to the lamps. It feels a bit awkward and artificial, even though I know it's just the way the clouds were at the time. If the clouds had been a bit less orderly there would have been a better contrast with the rhythm of the lamp-posts, but you couldn't control that, at least not without sacrificing the gorgeous lighting and colors. I love the color, I think it's the strongest element of this photograph. The yellow lamps really pop against the blue-violet clouds.
